Is dapsone safe to take during pregnancy?

Answer 1

You really need to ask your doctor this because there's no sure yes or no. This is what they say on Drugs.com (a very good site):

If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using Dapsone while you are pregnant. Dapsone is found in breast milk. Do not breast-feed while taking Dapsone.

Dapsone has been assigned to pregnancy category C. There are no animal data or controlled data in human pregnancies. Experience with dapsone during all trimesters of human pregnancy has not indicated an increased risk of fetal abnormalities. Dapsone should only be given during pregnancy when benefit outweighs risk.

Dapsone is excreted into human milk. Hemolytic reactions have been reported in neonates. Due to the potential for serious adverse effects in a nursing infant, a decision should be made to discontinue nursing or discontinue the drug, taking into consideration the importance of the drug to the mother.
